solve 3x+7/7

OpenStudy (anonymous):

(3x+7)/7 ? or 3x+7/7?

OpenStudy (anonymous):

it is written as a fraction 3x + 7 over 7.

OpenStudy (nowhereman):

What do you mean by 'solve'. What you gave is only a term.

OpenStudy (anonymous):

Yeah ...that was on a test. Can you solve for x or is it just a term?

OpenStudy (nowhereman):

Well you can consider the function \[x ↦ f(x) = (3x+7)/7\] and calculate the inverse function, which would be \[y ↦ f^{-1}(y) = (7y-7)/3\]
